Israeli Prime Minister Benjamin Netanyahu would pay the price for accepting an invitation by the US Congress to speak about Iran’s nuclear program, an American analyst says.

“It’s a breach of the Constitution, breach of diplomatic protocol, and I think Netanyahu would pay the price in much chillier relations with the executive branch at least under the Obama administration,” William Jones from Executive Intelligence Review told Press TV on Sunday.

“This will also have repercussions far beyond that,” he added.

Last month, Boehner invited Netanyahu to speak about imposing further sanctions against Iran at a joint session of Congress while the five permanent members of the UN Security Council plus Germany and Tehran are negotiating to reach a final nuclear agreement.

The invitation came despite President Barack Obama’s threats to veto new Iran sanctions legislation.

Boehner invited the Israeli leader without consulting with the White House.

“This was a breach of protocol and also really possible constitutional breach because the foreign affair of the United States is primarily conducted by the president of the United States and by the executive branch and of course President Obama was not in favor of this,” Jones said.

Netanyahu, who is strongly against a nuclear agreement with Iran, has been repeatedly trying to persuade congressmen to vote in favor of additional sanctions against Tehran.

President Barack Obama would not meet with Netanyahu during his trip to Washington, according to the White House.
